Q4 2025 Earnings Call — February 26, 2026

Analyst Stephen Gengaro (CIFL): Thanks. Good morning, everybody. You know, my first question is on the guidance and maybe two parts. One is, a couple months ago, you had a pretty high expectation for the fourth quarter, and clearly you fell short. And now we're looking at, you know, a pretty big ramp in 2026. How do you think about the components of guidance and sort of de-risking the parameters you put out versus guidance historically?

Executive Name: Morning, thanks for the question. First, like, you know, you look at the range as I talked about when we talked about the guidance in of itself. We're looking at the improvements that John has implemented coming out of fourth quarter, looking at the backlog of orders that we have to get to the bottom end of the range, then looking at the opportunities that we're working on, the fact that we're bringing a new line in to give us the top end of the range. But we've tried to really look at how we can change our discipline as a company to not have happen what happened in 2025. So the range is 100 million, the midpoint is 350. What hasn't changed about the company is the demand that's out there for the product. What we're trying to do in 2026 is better control our scale, get the manufacturing throughput quality and margin expansion that we need, and really look at where we think we can land without going for a degree of difficulty that's a 10, but coming in with something that we can manage to over time.

Analyst Stephen Gengaro (CIFL): Now, that's helpful. And then just, I imagine this is correct, but when we think about the quarterly growth, I mean, I would imagine the 1Q would be above 4Q, but the low point and then escalate throughout the year. Is that a reasonable pattern?

Executive Name: Well, look, Stephen, so part of what we have coming in, and, you know, we don't give quarterly guidance, but from a standpoint of coming into the year, you know, we're coming off a high point. We're delivering the customer schedules. I think we'll be around the fourth quarter number as we look at, like, what we have to deliver to customers. And there's also commissioning revenue in there as well. And then from there, sequentially grow.

Analyst Julian Dumoulin-Smith (Jefferies): Hey, good morning, team. Thanks for the time. Can you guys comment a little bit about what exactly those bigger projects that you're talking about are? Like which ones in particular seem particularly ripe, right? Again, just to maybe track against the milestones this year and what would materialize? And also, if you can speak a little bit against, you know, you've got a materially larger backlog in aggregate. What's the duration of that backlog when you think about it, just given that, you know, call it 300 of it is burning off this year, if you will?

Executive Name: Julian, great question. Look, I think we go back on the material large stuff. But look, I think we all know the industry needs power, needs power quickly. But at the same time, we still operate in a framework where approvals and, you know, queues are long, so we're kind of hedging that. But like, you know, Nathan talked about two large projects in NYSERDA that, when approved by NYSERDA as part of their bulk storage, would go into delivery almost immediately. So that's two of them in there. We've talked about PJM and what we're doing with Talon. There's other projects that we have that we haven't discussed with large hyperscalers that could potentially come in. And then Nathan talked about what appears to be, when you look at the surface, they look like small projects, but they're small projects with a big pipeline of opportunity that you deliver and grow and continue to deliver. And we just got to work through that. We'll keep everybody updated on that as we move forward from there.

Analyst Julian Dumoulin-Smith (Jefferies): Got it. And then just if I can follow up there, the defense space seems intriguing here. Can you comment about that end market and the opportunity you see there? What does a project look like in that space, size, duration? And just even elaborate a little bit more about what you guys were talking about a second ago in the timing of seeing some of that come to fruition.

Executive Name: So defense, I think you start off with NDAA, which is how the Defense Department of War purchases. In the NDAA, they're being told to buy American products, and I think we have that American product. As we go through that, there's a lot of things we have to go through as far as working with different branches of the government to get approval. I think a big thing that helps accelerate us is the due diligence process that we went through with the Department of Energy to get our loan. But like we're working through across all branches of the military to see what the needs are. And like what we're looking at is what do they need and they also have, there's also large power growth that they have and how do we meet those needs and then we go through and show them how the product is. But also as you work with the military, there's things that we're doing to make sure that we hit all their requirements because we want to hit the ground running. But that's something that we'll continue to work on and we are working on and we do spend a significant amount of time down in Washington walking everyone through what the technology is capable of.

Analyst Julian Dumoulin-Smith (Jefferies): Got it. Excellent. Thank you for that. And then lastly, if I could just ask just given where you are coming out for 26, how do you think about the ramp of line three and four, right? So, you know, how do you think about when and the timing and scaling of that, right? Obviously you got line one and now line two here, but three, four, four of a 27 question, right?

Executive Name: And I think Julian, like this goes back to disciplined execution, right? It's a great question, right? So John, John's taking us into a new building and the new building changes the game from a throughput efficiency and cost. Turtle Creek is a fully functioning factory that's up at 2 gigawatt hours of production. It hit its nameplate capacity coming out of 2025. But if you have a lean mindset, you're constantly looking at how to get things better, how to improve on things. That goes with how you operate your manufacturing, but also how you implement capacity expansion. So what we've told John is come up with a plan that we can execute and implement lines within the window of when a customer orders to when they ship. So as things come in, we'll be able to do that. What John has done in his time, not only did he increase output 80% in the fourth quarter, if you look at quarter over quarter sequential manufacturing output, he also went in and revamped our automation partnerships.

Got us in with tier one automation providers, broke up how we were doing the different pieces of that and positioned those suppliers to be able to come up with a framework agreement approach with them where we can put a signal in to them and they can deliver faster than what we're doing on line two today. Line two today, part of what's happening there is it's a new building and there's a lot of work that we got to go through and we want to make sure that we get that right and we get that ramp right and the transition and balancing between the two facilities.

Analyst Mark Straus (JP Morgan): Yeah, good morning. Thank you very much for taking our questions. I'm just curious if you can comment on the competitive environment that you're seeing recently. Obviously, you guys are making good progress with your backlog, but one of your publicly listed peers that's traditionally in lithium-ion, they have really been talking up their long-duration pipeline the last couple of quarters. You know, there's a very large project, long-duration project up in Minnesota that just recently got announced. Just kind of broadly speaking, I know those are completely different technologies in both of those cases, but just kind of broadly speaking about the competitive environment would be great.

Executive Name: Mark, I think first off it points to what we're showing in our backlog about longer duration discharges coming to fruition. I think it's great to have other companies that are doing it because it just goes to show that what we've been talking about for five years, the market's now there. I've said this many times, there's many different use cases and I always draw the correlation of energy storage is going to look like gas turbine technology over time. You have different types of gas turbines that do different things with different efficiency points. So I think what was announced in Minnesota, delivery in 2028, is a great example of people looking for longer duration energy storage, longer than what we do. At the same time, Nathan showed our pipeline is up above 40% for longer duration. And it's now becoming 40% of our pipeline. Sorry, I misspoke. But it's becoming more and more. And I think established players, there's a market out there for that product. I think we've come up with the work that Francis has done and the team. We've come up with a solution that delivers in that direction, four to 16-hour spot, which is going to be very important.

And look, we've been running load profiles here in our test facility in Edison, New Jersey, using the load profiles of data centers, and our technology matches up great with that. So we're encouraged by that, but there's a lot of demand out there, and I think it's great there's other players. It's going to be a competitive marketplace, and I think we have a product that competes.

Analyst Craig Shearer (Tui Brothers Investment Research): Good morning. Thank you for taking the questions. Can you opine on the potential margin deltas, gross margin deltas between U.S. and international orders? Does American-made help in any way internationally to the degree some trading partners want to right-size trade balances on a national level? And can you give some color on the timeline for that foreign power company national lab testing and the level of prospective order flow should they deem you're having the most optimal solutions?

Executive Name: Craig, just a couple of things inside of that. I think where we're seeing interest in our product internationally has less to do with politics and more to do with performance. I think people are looking at what the product delivers and less about trade balances. I think having a product where we go through and talk about the intrinsic value of it is what's attracting our customers, whether that's domestic or international. I think we're starting to plant seeds, starting off in Germany, and obviously we have a big pipeline of opportunity in the UK that Nathan talked about. Just on your last point here, the customer that Nathan talked about is a global utility that's doing testing in the United States at a lab that is tied to a project for the NYSERDA program. By the way, that testing is great. We love doing that because it gives us data to show people about how the product performs and put this through its paces. Doing stuff like this, that's what brings out intensity and improved performance on the product that we have out in the field.

Analyst Craig Shearer (Tui Brothers Investment Research): And would one assume that international sales are going to be slightly lower gross margin?

Executive Name: No, I wouldn't assume that.

Analyst Craig Shearer (Tui Brothers Investment Research): Okay. And my last question, and I apologize if my quick math is incorrect, but it looks like you burned through maybe $65.75 million in operating cash flow before working capital changes in the quarter. Thoughts about tempering that bleed as you move in the positive gross margin in the second half of 26?

Executive Name: Look, our goal, as Nathan talked about, we've capitalized the company. We are focused on being good stewards of that capital. I think as you look at that, one of the reasons why we removed the going concern for the company in this quarter is that we see a trajectory to be able to manage the company strategically and for the long term. And then obviously, like, there was a ramp into a build. There was a ramp into a build plan that then levelizes, but then will ramp again. So we managed through that, but, like, as we look at where the company is, we have cash to be able to grow it over the long term.

Analyst Jeff Osborne (CD Callen): Thank you. Just a couple quick ones. I think last quarter you mentioned that the yield on the bipolar line that started, I believe, in July was 98%. I was wondering what the fabrication yields were in the fourth quarter.

Executive Name: Yeah, John, take that one.

Executive Name: So the bipolar yields in the growing from there. So we're basically, within January, hitting the target. We've reduced that significantly, and we'll continue to do so. And we did not anticipate that with the automation. The goal for that automation is 97% for special. And we're well on our way there.

Analyst Jeff Osborne (CD Callen): Perfect. And then can you just touch on, spend a few seconds on what sort of field performance has been, safety, reliability, commissioning schedules relative to expectations?

Executive Name: Yeah, so Jeff, I don't know if you heard, I don't know where we dropped off before. Look, we continue to go through and execute out in the field, bringing a new product online, operating out, operating. We were doing our operations meeting this morning and continue to see good cycles out in the field, as Francis talked about. We continue to learn on each cycle and incorporate those things back into the install base from a commissioning cadence standpoint. It's a mix and cadence of things where there's permitting challenges, there's bringing the site up to speed, there's getting our stuff up and running, there's integrating everything, and we work through that with the customer on a customer-by-customer basis. But if you go back to that page I showed, we ship to 10 customers, recognize revenue on 18 customers, and that ties back to the commissioning that we have.

Analyst Jeff Osborne (CD Callen): And just very quickly, are you capturing higher price as the duration use case extends out to six, eight hours and beyond, or is pricing consistent with a sub-four-hour relative to longer duration?

Executive Name: Well, I mean, Jeff, I think it all depends on how you look at that. I think when you look at the value proposition of EOS and you look at our ASP in the backlog, the ASP in the backlog is higher than what you would expect for a shorter duration product. What we do is we sell on a levelized cost of storage basis, which is a little bit higher on the CapEx side, but a lot lower on the operating cost side. And that's what the customers evaluate to make their purchasing decisions.

Executive Name: Thanks, Jeff. I am showing no further questions

at this time.

I would now like to turn it back to CEO Joe Misrandolo for closing remarks.

Executive Name: Yep. Thanks, everyone. And again, thanks for the question and the continued engagement. A couple points I want to close with. First, you know, demand for long-duration, domestically sourced energy storage is not a question. The grid is changing. The load growth is real. Whether it's AI electrification, industrial reshoring, these are structural changes to the power grid in the United States, and they're not cyclical. The market is moving towards solutions that match what we bring to the market, and that's how we've positioned EOS for the long term. Second, 2025 was building a foundation, strengthening our balance sheet, scaling manufacturing, standardizing our product architecture, improving operational cadence. We delivered great revenue growth. It reflects the progress that we've made. It's not linear yet, but it's directional and it's improving. Third, 2026 is a year where we have to show disciplined execution. Our guidance reflects what we believe we control as we sit here today. We'll keep everybody updated as we go through the year and where we wind up.

I feel good about where the team is positioned and execution improves predictability improves so we know we've got that's what that's ultimately where we need to focus on and that is where the team is focused on a day-to-day basis and then profitability for the company look it's a scaling equation you know on an automation you know how we move material efficiency bring a lean mindset finding waste eliminating waste resetting it going back and doing it again and again again and you see the sequential improvement in margin that we need to continue until we become margin profitable, and that's the goal of the company to deliver long-term, valuable shareholders and customers. Look, we strengthen our liquidity. It helps us operate the company more strategically. It gives us runway to be able to execute. EOS is an infrastructure business, right? We are infrastructure businesses are built on discipline, consistency and operational trust. That's what we're building and that's what we have to show and deliver. We appreciate the questions and the focus and really the attention to EOS across the board of all of our stakeholders.

We look forward to demonstrating this continued improvement and progress quarter over quarter as we build a great energy infrastructure company. Thanks for listening today. Thank you for your participation in today's conference. This does conclude the program. You may now disconnect.

Quarter 2

Q3 2025 Earnings Call — November 6, 2025

Analyst: Julian DeMolen-Smith (Jefferies): Hey, good morning, team. Thank you guys very much for the time. Nicely done, I've got to say.

Management: Thanks, Julian. Absolutely. Nice to chat with you guys. Maybe just to kick things off here, I know you tweaked the 25 guide here, but if you think about the quarter-over-quarter run rate and trajectory, I know you articulated this more in operational terms in your prepared remarks, but how would you think about as you exit 25 with that 4Q that's implied with your full-year 25 guide? How do you think about that ramping into 26 here and what that trajectory suggests? If you just look at, you know, the 2Q, 3Q, 4Q trajectory on top line, I'm just really curious how you think about that revenue trajectory going into 26 and the ability for your commercial.

Management: No, thanks for the question. So in my prepared remarks I talked about, so Q3 we were at 15% capacity utilization and if we look at going forward, we'll exit Q4 running our complete asset base 24-7. So you're looking at going from a 15% capacity utilization to 90-plus from a capacity utilization standpoint. A lot of work was done in Q3, installing capacity, training our workforce, training the additional shifts, and all the costs associated with it. So as you fast forward, all the ramping will be done. So as we enter Q1, at the very start, we'll be at OEs higher than 90%, and we'll be fully realizing and utilizing the capacity. Thank you.

And then, Julian, on the revenue side, I mean, I'll let Nathan kind of add some comments there because that kind of falls into his two hats.

Management: Yeah, no, I mean, John did a good job of laying out what we're doing this year. I think as we look forward into 2026, we're seeing a tremendous amount of activity in our pipeline, right? Pipeline's up 21%. 22% of that now is data center activity. We talked about kind of the sales cycle and how these things mature over a period of months, even quarters. And we continue to see very strong activity in the pipeline as we move forward. Good news is John's capacity expansion now can be moved in three-month increments as the orders come in. And I think we're going to see new orders come in. We're going to add capacity to line up with those orders. And I see consistent revenue growth over time.

Yeah, Julian, the thing I would add on the pipeline and orders side, we've always been very conservative about what we do with our backlog and our orders pipeline. Nathan's got some things going on that are MOUs that we haven't been able to announce names yet, and he continues to work with Justin and the entire team to get some of these hyperscalers to go from an MOU to firm projects. And we really only want to talk about them when we close them and there's project names that we can talk about, like we did with Frontier.

And I'll make one more point. So you think about all the assets we're installing. So we're learning as we go, right? So first bipolar line comes in, took us several weeks to get it up and running. Six and seven that we just got up, now we're talking days. The same thing will fast forward to when we launch line two in the spring. All those learnings, so we're able to shrink the ramp, shrink the time to get up to full capacity. So everything we're doing now, we're learning. So with the data, we're going to be able to aggressively move forward much quicker than we are right now.

Analyst: Julian DeMolen-Smith (Jefferies): Awesome. And guys, if I can take sort of the natural extension of that last question, how are you thinking about the ramp here, right? I mean, it's pretty phenomenal what you've just achieved in the last six months here, as you just described. How do you think about the cadence of ramping further lines? And then also related to that, how do you think about the financing side of that, right? So you've got the 43 million from Cerberus, you have the 24 million award, you've got unrestricted balance of 60, you've got an ability to tap DOE. How do you think about financing that against potentially what seems like an accelerated ramp on CapEx? I don't want to put words in your mouth when I say accelerated, but I'm curious on how you think about just teeing this all up and setting expectations.

Management: I think, Julian, I kind of put the puzzle together there that you're laying out. You know, we have a loan from the LPO, from the Department of Energy, that finances four lines, right? And we're going to line two. What John's trying to do and what we have to do is reduce the cycle between starting and getting a line up and running so we start producing revenue off of that so that the capital requirements, in effect, become operational versus financial. That being said, we're in a moment of time here where the industry and the world needs our product. We've got to be able to ramp into that as quickly as possible. I've said many times, we don't want underutilized capacity sitting around. But we're looking at all this. And what John's put together from the different automation suppliers that he now has and breaking this up into pieces and getting everybody focused on delivering to that goal, we'll be able to get that capacity online in 90 days, which is well within the cycle time of how Nathan's selling the product. So part of it will be what we already have in place. Other things will come from operations and deposits from customers as we close orders. And then we'll look to be opportunistic, if need be, for growth capital if we have to.

Analyst: Julian DeMolen-Smith (Jefferies): Awesome. Excellent. Sorry, one last tweak here. You talk a lot about operational metrics, but it seems like the latest quarter ASPs went up materially. Again, you tell me if we're reading that right. And you also flag, I think in the queue here, a concentration with like 80 plus percent tied to a single customer. This is not the same customer as you guys have been concentrated to in the past, I presume. Can you talk to that just a little bit about the ASP dynamics and the customer maybe of late?

Management: Yeah, we talked about this a little bit last quarter as well. So Q2, I think, was the anomaly because we had one strategic customer that was a drag on revenue in Q2. What we're seeing in Q3 was revenue rates reverting back to what we view as a more normal run rate. And then deliveries in the quarter, I mean, it was five individual customers. You know, they're not all equally weighted, but I would say the customer base that we delivered to in Q3 was representative of what customer base would look like going forward.

And, Julian, I just want to add two points on top of what Nathan just said. You know, ASP, like you could – I try not to pick individual contracts for managing a portfolio. Like any portfolio, highs, lows, but you've got to get your average where it makes sense, and the average of the portfolio is up. And it's up because people are seeing the value of the technology. Now, on this strategic customer that we talked about last quarter, look, we're getting data from that system out in the field, and it's on that page that we talked about. and the data is phenomenal. So I look at that as kind of an investment in our future where we needed to get Z3 out in the field at scale and see it operate, and it's delivering on those results. So it's a mix of all things, but the overall portfolio of the order book, ASP is higher than what it was.

Analyst: Julian DeMolen-Smith (Jefferies): Yeah, absolutely. I'm very curious to see some of these strategic partners in there in all the states in the coming weeks. All right, guys. Thank you very much. All the best. I'll leave it. I'll pass it over.

Analyst: Stephen Jengero (DeFoe): Thank you. Good morning, everybody.

Management: Hi, Stephen. How are you?

Analyst: Stephen Jengero (DeFoe): I'm good, thanks. So I think two things for me. One is just to follow up on the last question. I'm not sure how much you want to say, but you talked about sort of the average selling price kind of across the portfolio. Is that right? How does that look in the backlog and the recent awards that you're booking relative to kind of what you're realizing now?

Management: Look, I mean, you can do the math on the backlog page, right? I mean, you can see total dollars and total gigawatt hours and how that's trended over time, and it's stayed pretty consistent over time. I mean, we're not seeing long-term. I think the revenue rates that we've realized and expect to realize going forward are going to be pretty consistent. When you get larger orders, you know, we're working with customers. Okay, what is our cost curve doing? What can we do from a large volume buy perspective? You saw the chart we showed on page eight, I think it was, where you see margins improving over time. You see net margins improving over time, you know, as we continue to scale the business. But we think we're going to turn the corner here and get to positive contribution margin into this quarter. Positive gross margin exiting Q1. on a path to profitable, positive EBITDA after that.

Management: And, Steve, what I would add on top of that, you know, part of my job is handing out the targets to people, and the orders that were recently closed are well within the ASP portfolio target that Nathan has as CCO.

Analyst: Stephen Jengero (DeFoe): That's helpful because I couldn't do the math on the post-quarter announcement. But that's fine. Thank you. And remember, the stuff that we're talking about, Stephen, you know, that's post-Post quarter close, that happened after the quarter, after 3Q.

Analyst: Stephen Jengero (DeFoe): Yeah. The other one I had is, it's around the margins, but it's around the cost side. When we think about the progression of margin and some of your bigger costs that go into making the product, how should we, what are the necessary levers that get you to gross margin positive? Is the supply chain improving? Is it the COGS coming down per unit? Is it just scale? Like, is there a color you can give us around how to think about the cost structure? That's the biggest, as you've been successful with the ramp and the backlog growth, that's the biggest question we get from investors pretty consistently is, you know, what does this look like at scale from a profitability perspective? So I'm curious if you could give some incremental color.

Management: Yeah, so from a cost perspective, I already talked about the asset utilization. The same thing is true here is with our suppliers. So they've had to put a lot of assets in place to be able to support this ramp. So as we ramp, they're ramping. So they're seeing cost optimization. They're seeing cost absorption, which will translate in cost reduction from a parts situation. Then you kind of look at labor costs. So a lot of what we're focused on right now is taking costs out and making things more efficient. So I'll give you one example. We were focused on our gate. And with that, we were looking at travel time, material, the way they're presented. Basically, all aspects of that operation came in on one weekend, completely changed the way we were doing that operation. And the five days prior to what we did versus the five days ahead, we doubled the output. So the work we're doing is not having incremental gains, it's having step function gains. So we talked about labor. You talked about utilization. Again, we'll be at 100% utilization coming out of Q4. So you're going to get mass asset. Then it's about taking cycle times out. So we've got a heavy automated process.

So if I can take 10 seconds down to 9.8 seconds, down to 9.6 seconds, and that work is absolutely doable. Again, you keep moving it forward. The one thing I like about being here is where I came from, I had thousands of different products. So the focus would shift every day. Now I have to come in every day and focus on the one product. So this journey never ends. We will continue to look at all of our cost buckets and continue to put projects together that'll close those out. We right now, just to take the material cost out, forget cost savings and what we're asking from the vendor, we've got 61 different projects that we're doing right now to take the amount of parts that we have out, to take the cost out. 61 projects, and all of those projects will be closed before we execute two. So that's the way I kind of think about it.

Analyst: Stephen Jengero (DeFoe): Okay, great. No, thank you for all the color.

Management: Thanks, Stephen.

Management: And there are no further questions

at this time.

I will now turn the call back over to Joe Mastrangelo, CEO, for closing remarks.

Management: Thank you. Thanks, everyone, for listening. Look, one thing I want to talk about here in the closing is the project that Nathan and Justin closed with Frontier Power because this kind of lays out another strategic puzzle piece for us as we grow the company. We met Frontier back in January. Nathan and Justin met them at a trade show in the UK. We developed the relationship, signed an MOU, got a project pipeline, and every week we meet with Cerberus and we go through where we are in cash, where we are financially, how we're doing in performance, and we look at Frontier not as a transaction but as a platform. Cerberus financed Frontier because we view this as experienced operational leadership in the industry that can help us build a platform to expand out in Europe. We're excited about how that's going to look as we move forward and really look forward to partnering with the team at Frontier.

At the same time, we're looking at what John's doing operationally, and you've heard it really, you know, it's fun working with him. It's great having him on the team and seeing what he's been able to deliver and the whole team underneath him. We just have to keep growing and keep focused and knowing that, the industry needs our product. We've got to continue executing, and we've got to keep making this simpler and easier to do business with. I look forward to keeping everyone updated on the progress. I want to thank everyone for listening today. Thanks a lot. Talk to you soon.

Management: Ladies and gentlemen, that concludes today's call. Thank you all for joining. You may now disconnect.
